About CheckTxt
Built from the ground-up to solve the fraud problem the rest of the industry left behind.
CheckTxt was built by a team that had spent over 60 years inside the security industry — across some of the most influential companies the space has ever produced. Fortify, acquired by HP. AlienVault, acquired by AT&T. Phantom, acquired by Splunk. WhiteHat Security, acquired by Synopsys. Appthority, acquired by Symantec. Valimail, acquired by DigiCert. Synopsys/Black Duck. Contrast Security. Bolster.
Nine acquisitions between us.
Categories created.
Enterprises protected.
And yet, everywhere we looked, the same blind spot existed. The people outside the firewall — employees on personal devices, customers on personal phones — were completely unprotected. No tool was built for them. No budget owned them. The channels attackers used to reach them — SMS, email, messaging apps — fell outside every security stack we’d ever worked on.
We designed CheckTxt from the ground up to be different, to protect people, not just infrastructure.

The Mind Behind CheckTxt
Jack Marshall has spent his career building technology companies that solve problems others overlook.
Starting in the late 1990s, Jack founded Photoloft — one of the first online photo-sharing platforms — taking the company public before its acquisition by Canon. Over the next two decades he held leadership roles across some of the most influential cybersecurity companies in the industry, from Fortify and AlienVault to Contrast Security and Bolster — companies that collectively shaped how enterprises think about security.
But it was a text message to a family member that sharpened everything into focus.
Not a sophisticated attack. Not a nation-state threat. Just a convincing scam targeting someone he loved — someone with no firewall, no security team, and no way to know whether to trust what was in front of them. It was the same blind spot he’d seen inside every enterprise he’d ever worked in, playing out in real life, on a personal phone, in a moment that mattered.
That’s what CheckTxt is built to prevent.
“We don’t just protect systems. We protect people.”
